'I'he invention pertains to Winding machines known as spoolers, for winding yarn from bobbins onto spools or yarn carriers to form yarn masses or cheeses and has particular reference to the uniform adjustment of the yarn cleaning or clearing devices of the spooler, through which the strands of yarn pass in traveling from the bobbins to the cheeses.

Yarn clearing devices as commonly constructed provide openings for the passage of the yarn, and are made adjustable so that the size of the openings can be changed in accordance with variations in the size or gauge of the vyarn being spooled. In some mills the size of lments has been to adjust the size of the open-l ing in each of the clearing devices by the use 'of a feeler gauge in the opening to determine the extent of movement to be imparted to the adjusting screw or other means provided for that purpose. The accurate adjustment of the clearing devices requires the exercise of great care, and where a large number of devices are to be adjusted a substantial amount of time is consumed during which the machine must be idle.

. With the foregoing in view, the primary object of the present invention is to provide for the adjustment of the clearing devices of a spooler rapidly and uniformly in order to facilitate and expedite changes in the size of the yarn being spooled.

Another object isto provide for the uniform adjustment of a plurality of clearing devices by means operative to afford a positive indication to the operator when each of the devices has been adjusted to a predetermined setting.

A further object is to provide an adjustable setting device adapted for use in adjusting a plurality of yarn clearers uniformly and expeditiously. ,y

Another object is to provide in a yarn clearing device, means of an advantageous character for adjusting the size of the opening through which the yarn passes in traveling from the bobbins to the cheeses.

Fig. 8 is a sectional view taken approximately in the plane of line 3 8 of Fig. 6, the manuallyav operable device of the setting means being shown in broken lines.

Referring rst to Fig. 1 of the drawings, a plurality of clearing devices 9 are shown in operative relation to strands of yarn d passing from 1,25 bobbins I0 to cheeses Il in peripheral contact with a driving drum I2. The clearing devices are mounted upon bobbin pockets I3l directly, above the bobbins. Except for the adjusting means, the clearing devices shown in Figs. 2 to Il y 30 are of the construction disclosed in the patent to Peterson No. 1,663,856dated March 27, 1928.

Generally stated, each of the clearing devices 9 comprises a pair of blades lll carried by spaced parallel rock shafts l5 and disposed in V-shaped relation with the free edges of the blades held in spaced parallel .relation to form an opening I6 (Fig. 2) for the passage of the yarn strand a. The shafts I 5 are mounted in a suitable U-shaped frame il' also carrying parallel rods E8 for guiding the yarn. The frame I1 provides two uplright parallel standards I9 (Fig. 3) in which the rods I8 and the rock shafts l5 are mounted. The size of the opening i6 formed between the blades I4 of each clearing device must be adjusted in accordance with the size of the yarnr to be spooled. Such adjustment is accomplished by means of an adjusting element preferably in the form of a cam 20 acting upon a follower, which in this instance is a plate or slide 2l.'

'In the embodiment shown in Figs. 2 to 4,`the cam follower slide 2| engages with a spreader bar 22 interposed between and acting upon the blades I4. As herein shown, the bar 22 has one lend anchored in one of the standardsv I9 and the other end projecting through an elongated opening in the other standard into position between the blades at inner ends thereof, as shown in Fig. 3.

The cam is arranged for angular movement by means of a rotatably mounted stud 23, and the follower slide 2I is held in engagement with the cam by means of a spring 24 acting upon the spreader bar 22 which in turn bears upon a depending portion 25 of the slide 2l. The cam 20 and the parts immediately associated therewith may be supported in the frame I1 by any suitable or preferred means.

In the present instance the cam is disposed within an opening 26 in the' slide 2I and bears against an inward projection 262L at the lower side of the opening. The cam is suitably fixed to the stud 23 as by being pinned rto a collar 21 rigid with the stud forwardly of the slide.

The stud is rotatably mounted in a bearing sleeve 28 carried by the upper one of two frame plates 29 which` are interposed between the vertically spaced guide rods I8, the plates being suitably grooved at their top and bottom edges to conform with the circular contour of the rods. At its rear end the stud is threaded to receive clamping nuts 30 acting upon a spring Washer 'screw 45. rpressed plunger 46 adapted for coaction with a by a plate similar to the plate 29.

For the purpose of making like adjustments of theclearing devices of a spooler, the present invention provides a setting means comprising the adjusting stud 23 and an adjustable setting device 36 with coacting stops on the setting device and the cover plate 33 of each of the clearing devices.

In the present instance the device 36 is in the form of a separate implement adjustable in accordance with variations in the size of the lyarn tov be spooled and adapted to be applied -to the'adjusting studs 23 of the various clearing devices. As shown it comprises a shank 31 equipped with a suitable handle 38 and carrying "a head 39 providing an irregular socket 49 for coaction with the stud 23. In the present instance the socket is of cylindrical contour except for a flat side 4I (Fig. 5), and is adapted to iit over an enlarged forward end portion 42 of the stud 23 which is complemental in shape to the 4socket 49.

The socket 49 of the setting device is formed in a sleeve-like member 44 fitting within the head 39, the parts being adapted to be secured in various angular relations by means of a set The head 39 also carries a spring hole 41 in the cover plate 33 when the parts are in the relation shown in broken lines in Fig. 4.

It will be seen that due to the irregular shape of the socket 49 and of the stud portion 42, the setting device 36 can be applied to the adjustment of a clearing device in only one predetermined angular relation of the socket member 44 and the stud 23.

Also it will be seen that the plunger 46 of the setting device and the hole 41 in the cover plate constitute coacting stops positively determining the extent of angular mokthe operating stud 23.

tion imparted to the cam 29 by the operation of the setting device, and for any given position of the stop or plunger 49 relative to the socket member 44 in the head 39, the cam 20 of any of the clearing devices may be adjusted to change the size ofthe opening I6 `corresponding to the adjustment of the setting device. All that is necessary, therefore, is to set the socket'in the setting device according to the size of the desired opening I6 in the clearing device, and then turn the adjusting studs of the various clearing devices until the coacting stops 46 and 41 interengage, whereupon the blades I4 of each of the clearing devices will be adjusted to the same size of opening. To facilitate `the relative adjustment of the plunger stop 48 and the socket member 44 for any given size of yarn, the face of the head 39 may be provided with a suitable dial 48 (Fig. 5) and the face of the socket may be pro-vided With a coacting index point 49.

The use of cam means for adjusting the clearing devices is advantageous in that it renders it possible to obtain uniformly graduated variations in the size of the opening I6 of any clearing device for a corresponding angular motion of In each instance, the maximum range of adjustment of the o-pening is obtained by an angular movement of the stud and therefore of the cam 29 through 360, and as shown in Fig. 5, the graduations of the scale or dial 49 are spaced apart uniformly. Also by properly shaping the cam it is possible to compensate for variations in the movements imparted to the blades I4 incident to the angular relation of the surfaces of the blades engaged by the l spreader bar 22, it being observed that movements of uniform length imparted to the spreader bar would not- .effect corresponding uniform changes in the size of the'o-pening between the blades.

In Figs. 6 to 8, the invention is shown applied to a modified form of clearing device comprising a single blade 5I mounted upon a rock shaft 52 and movable therewith relative to a stationary thread guiding surface formed on a plate 53 to vary the size of the opening IG (Fig. 7) for the passage of the yarn. A coiled spring 54 surrounding the shaft 52 exerts a rotative force thereon in a ydirection to carry a transverse pin 55 into engagement with the lower end 0f a slide 2I' operable by means which in all material respects is like that described in Figs. 2 to 4. In this particular embodiment, the cover plate is in the form of a disk 56 having a depending arm 51 engaging in a slot 58 in a flange 59 projecting from the plate 53. Also the rear clamping disk 29' has a depending portion 32 slotted at 6I to receive a projecting portion of the pin 55 which acts to hold the shaft 52 against endwise movement.

It will be observed that the present invention provides for the uniform adjustment of a plurality of clearing devices in a spooler in a manner such as to simplify and expedite greatly the operation of changing the size of the yarn being spooled. With one adjustment of the setting device according to the size of the yarn to be spooled, as indicated by the dial on the face of the head 39, it is only necessary to turn the adjusting studs 23 of each of the clearing devices until the coacting stops 46 and 41 interengage. Such interengagement of the stops affords a posltive indication tothe operator that the opening provided for the passage of the yarn has been adjusted to the proper size for `the yarn 1 :necessary for. theoperator; to make .any accu-rate measurements or observations or to exercise any erations.
